Abstract

Selon des modes de réalisation, la présente invention concerne un procédé de recherche de mobile, un équipement de réseau et un équipement terminal. L'équipement de réseau détermine une PO en fonction d'une ID d'UE et d'un type d'accès, ce qui permet de réduire le surdébit provoqué par la recherche de mobile. Le procédé comprend les étapes suivantes : un équipement de réseau détermine une occasion de recherche de mobile (PO) d'un équipement terminal en fonction de l'identité (ID) de l'équipement terminal et d'un type d'accès correspondant à l'équipement terminal ; l'équipement de réseau envoie un message de recherche de mobile destiné au dispositif terminal au niveau de l'occasion de recherche de mobile de l'équipement terminal.
